Bad Controller?

I have a ten year old Orbit Control Star 6 zone controller, never had any problems. Only 4 zones are hooked up. The program that has been set is running inconsistently.

One day all four zones run correctly, the next day zones 1 and 2 run correctly and zones 3 and 4 never turn on. This morning zone 1 runs and zones 2, 3, and 4 never turn on.

Is this behavior being caused by a bad controller or is there something else to check?

Check your start times, and station run times. Sounds like you may have different start times or multiple programs running. Check if you have more than 1 program, such as A, B, or C. Check to make sure you only have one start time.

Thanks for the response. All the programming settings did check out OK. I reprogrammed everything from scratch anyway; let's see what happens.

I have a Nelson controller installed in 1999. Last year it was running during the day, in addition to the program I had it set for at night. Can you tell me if I set it to program B, does it run both A and B? If C, then all three? If this is the case, is it designed to set the front yard on program A and the back yard on program B, so you don't have to run your sprinklers for 4 hours in a row?

Or do I just have a bad controller?
